GE ENERGY STAR®

Qualified Refrigerators

•

GE refrigerators that have earned the ENERGY STAR are 30% more energy efficient than refrigerators that do not qualify for the ENERGY STAR, and 40% more energy efficient than conventional refrigerators sold in 2001.

•

All ENERGY STAR qualified GE refrigerators sold in 2007 were designed to avoid the emissions of more than 944,000 metric tons

of carbon dioxide over the course of their lifetimes compared to an

equal number of conventional refrigerators.

•

A single ENERGY STAR qualified GE refrigerator is designed to avoid the emissions of more than 2200 lbs of carbon dioxide over the course of its lifetime compared to a conventional refrigerator over the

same 13-year period; this is equivalent to the carbon dioxide absorbed in one year by 1/4 acre of trees in a southeastern US forest.

•

In some areas, the purchase of an ENERGY STAR qualified refrigerator may make consumers eligible for utility rebates.

ENERGY STAR®

Product Changes• New Main Board

Always refer to the label on the back of the cabinet or the part list.

Currently this board is specific to these E-Star models only.

These units use a variable speed compressor, single freezer evaporator and an electric FF damper control.


• New Main Board

J15 connector for inverter communication. This connector sends the 5-6 vdc

control voltage to the compressor inverter board.

Do NOT

install another variable speed or dual evaporator replacement board, the software is not compatible.

No compressor relay or compressor output wire.


Correct Board InstalledUnit knows it is a variable speed with damper control


Incorrect Board InstalledUnit thinks it is a single speed dual evaporator model using a three way valve. Note the run time and the fresh food temperatures. The refrigerator cycled off at a fresh food temperature of 14 degrees.

Needless to say, this will be an immediate call back!

Product Changes• New Compressor Inverter

WR55X10979


New Compressor Inverter

Old design

New design

The wire routing inside the new inverter has been changed to minimize the possibility of the wire cable damaging components on the pc board. The inverter

also incorporates a new DC connection plug. It is important to make sure the internal cable is routed properly upon replacement.


New Compressor Inverter

When replacing the inverter; set the inverter down beside the compressor and connect the inverter plug to the compressor.

While installing the inverter make sure the internal cable remains in the bottom of the enclosure so it does not touch the pc board.


New Compressor InverterDiagnosis of the inverter circuit is unchanged. For no compressor operation, check for 5 to 6 volts DC from the J15 1-2 red/white and the 120 volts AC to Black to Orange at the inverter.


ENERGY STAR®

Product Changes• Electric Air Damper ControlThe E-Star units use the electric damper control instead of the atmospheric door. This is the same damper control we have used in the past.

Resistance for each stepper motor is approximately 400 ohms read

at the J3 pins 1-2 and 3-4.

6 volts DC can be read on these wires individually by connecting

to the J2 pin 3 white wire “fans common”

while the damper is operating.


ENERGY STAR®

Product Changes• New Damper Air Flow ControlDue to the high efficiency of the sealed system; air flow between the compartments is restricted with a foam insert in the air supply duct. This insert is installed before the cabinet is foamed in. There are two different inserts depending on the cubic foot size of the cabinet. Looking in through the freezer side you will see a “2”

for 22 cuft

or a “5”

for 25 cuft

models.

If you have issues with uneven temperatures check for this insert. If it is missing or damaged, order kit number, WR49X10235.

Product Changes• New Door ClosureThe door closure/stop has been re-designed to be a one piece part. The bottom hinge and bottom closure cam has not been changed. The new part is secured

to the door panel with a single 5/16”

screw. The screw in the center of the closure serves no purpose

other than to add strength to the door stop.


• New Door Closure Kit

WR49X10236

If you have issues with the doors not closing properly, check the following.

• Is the cabinet properly leveled with some tilt to the rear. • Is there any scrubbing or deformity of the door gasket. • Is there sufficient food weight in the door bins. • Is the gasket lubricated along the hinge side.

If none of the above issues are found, order the following kit which will retrofit the unit to the previous design closure mechanism.

PROBLEM Side-By-Side refrigerators produced in Bloomington (metal liners) may experience doors hard to close, or won’t stay closed. MODELS AFFECTED Side-By-Side refrigerators produced in Bloomington (metal liners) between 02/09 and 06/09. REPAIR/RESOLUTION Steps to address this condition,

1. Lubricate the door gaskets and all hinge pins. 2. Raise the front of cabinet using wheel adjustments located behind the base

grille. 3. Inspect the door gasket to determine if the gasket is collapsed. If gasket is

collapsed, replace the gasket. 4. Inspect the door stop located at the bottom hinge area. If the door stop is

plastic, replace both Freezer and Fresh Food door stops using kit number WR49X10236.
